DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1: Please refer to Figure 1-Figure 6The utility model provides a technical solution: a power distribution cabinet with a replaceable sealing structure, comprising a power distribution cabinet body 1 and an opening and closing mechanism 2 rotatably installed on one side of the power distribution cabinet body 1.

[0031] A fixing ring 13 is fixedly mounted on the inner wall of the power distribution cabinet body 1 .

[0032] The opening and closing mechanism 2 comprises a door body 21 rotatably mounted on one side of the power distribution cabinet body 1 , a first slot 22 formed on the inner wall of the door body 21 , and a second slot 23 formed on the inner wall of the door body 21 .

[0033] A sealing mechanism 3 is installed on the inner wall of the opening and closing mechanism 2. The sealing mechanism 3 includes an inner rubber ring 31. The inner rubber ring 31 is clamped and installed inside the first clamping groove 22. The position of the inner rubber ring 31 corresponds to that of the fixing ring 13. A rubber pad 33 is also fixedly installed at one end of the inner rubber ring 31.

[0034] During the opening and closing process of the door body 21 , the inner rubber ring 31 is close to the fixing ring 13 fixed to the switch cabinet body 1 , and the fixing ring 13 abuts against the inner rubber ring 31 , thereby ensuring the sealing between the door body 21 and the switch cabinet body 1 .

[0035] The inner rubber ring 31 is located in the first slot 22 and has a certain friction force. After being installed in the first slot 22 , it is not easy to fall off, which facilitates installation.

[0036] The two rubber pads 33 are always fixedly mounted on the inner wall of the inner rubber ring 31 . When the inner rubber ring 31 needs to be disassembled, the rubber pads 33 can be held and pulled outward to remove the inner rubber ring 31 from the first slot 22 , and then a new inner rubber ring 31 can be reinstalled into the first slot 22 .

[0037] Two rubber pads 33 are installed, respectively located on both sides of the inner rubber ring 31, and there is a certain space between them and the inner wall of the second slot 23, which is convenient for the operator to hold and apply force. The rubber pad 33 is also located in the central part of the inner rubber ring 31, and the two ends are evenly stressed, which is not easy to cause the rubber pad 33 to break, and the use effect is good. The device does not need to use an additional mechanism to tighten the inner rubber ring 31, is simple to operate, and has a wide range of applications.

[0038] Example 2: Please refer to Figure 1-Figure 3 , Figure 5 A base 11 is fixedly mounted at the lower end of the power distribution cabinet body 1, and four sets of universal wheels 12 are arranged at the lower end of the base 11. The universal wheels 12 are arranged to facilitate the movement of the device.

[0039] The depth of the inner rubber ring 31 is greater than the depth of the first slot 22 , and the rubber pad 33 is arranged on one side of the second slot 23 . When the inner rubber ring 31 is installed in the first slot 22 , the inner rubber ring 31 is higher than the inner wall of the door body 21 , thereby ensuring the sealing effect between the inner rubber ring 31 and the fixing ring 13 .

[0040] Example 3: Please refer to Figure 4-Figure 6 A through hole 24 is also installed on the door body 21, and the through hole 24 is connected to the first slot 22. A one-way valve 25 is threadedly installed at one end of the through hole 24 away from the inner rubber ring 31.

[0041] During the installation process, one side of the inner rubber ring 31 is pressed into the first slot 22, and the air inside the first slot 22 is discharged through the one-way valve 25. Each opening and closing of the door body 21 can squeeze the inner rubber ring 31 until the air inside the first slot 22 is completely discharged, further ensuring the tightness of the installation of the inner rubber ring 31.

[0042] When the inner rubber ring 31 is replaced, the one-way valve 25 is first rotated to remove the one-way valve 25 so that air enters the first clamping groove 22 through the through hole 24 , thereby improving the efficiency of removing the inner rubber ring 31 and facilitating the replacement of the inner rubber ring 31 .

[0043] Example 4: Please refer to Figure 4-Figure 6 An outer rubber ring 32 is fixedly mounted on the outer periphery of the inner rubber ring 31 , and an inner cavity 34 is provided between the inner rubber ring 31 and the outer rubber ring 32 , into which a sufficient amount of gas is injected.

[0044] The length of the outer rubber ring 32 is greater than that of the inner rubber ring 31. After the door body 21 is closed, the outer rubber ring 32 is squeezed outward to facilitate flattening the outer rubber ring 32. Therefore, the gap between the inner rubber ring 31 and the first slot 22 is covered, further increasing the sealing effect of the device.

[0045] Example 5: Please refer to Figure 4-Figure 5 A squeezing mechanism 4 is installed at one end of the fixing ring 13 , and the squeezing mechanism 4 includes a plug-in ring 41 fixedly installed on the inner wall of the fixing ring 13 , and a fixing block 42 is fixedly installed at one end of the plug-in ring 41 , and the position of the fixing block 42 is adapted to the second card slot 23 .

[0046] An elastic member 43 is fixedly mounted on one end of the fixing block 42 , and an extrusion block 44 is fixedly mounted on one end of the elastic member 43 .

[0047] After the door body 21 is closed, the extrusion block 44 fits against the rubber pad 33, and the rubber pad 33 is squeezed into the second slot 23. The elastic member 43 is gradually compressed, and the two ends of the rubber pad 33 fit against the door body 21 and the extrusion block 44 respectively, and have sealing properties.

[0048] After the door body 21 is opened, the extrusion block 44 is reset under the action of the elastic member 43 , and the rubber pad 33 is taken out from the second slot 23 , which is convenient for the operator to replace it later.
